Summary: In this study, the prevalence of insomnia, study engagement, studyholism, and bedtime procrastination among undergraduate students were examined. The results showed a high prevalence of insomnia, studyholism, and increased study engagement. Female students reported higher levels of studyholism and bedtime procrastination compared to males. Insomnia was positively related to studyholism and bedtime procrastination. The study highlights the interplay between insomnia, studyholism, and bedtime procrastination, emphasizing the need for increased awareness of insomnia.

Summary: Overall, the study found that increased smartphone use during the COVID-19 pandemic was associated with higher levels of insomnia, anxiety, depression, and bedtime procrastination. Female students, unhealthy food consumption, insomnia, anxiety, depression, and bedtime procrastination were significantly higher in groups with 6 or more hours of smartphone use. Logistic regression analysis revealed that female gender, overweight, insomnia, and bedtime procrastination were significant predictors of 7 hours of phone screen time.

Summary: Medical students' impulsivity, including attentional, non-planning, and motor impulsivity, directly affects their cognitive capacity decrease. Attentional impulsivity also indirectly affects cognitive capacity decrease through smartphone addiction, academic procrastination, bedtime procrastination, sleep insufficiency, and fatigue. Non-planning impulsivity indirectly affects cognitive capacity decrease through academic procrastination, bedtime procrastination, sleep insufficiency, and fatigue.

Summary: With the widespread use of smartphones, smartphone addiction behaviors are becoming increasingly common. This study investigates the overuse of smartphones before bedtime and predicts smartphone usage based on different behaviors, using artificial neural networks. The findings suggest that smartphone addiction is influenced by the usage time, with shorter usage periods and longer usage periods more likely to lead to addiction. Short video watching and gaming were found to be particularly associated with smartphone addiction.

Summary: This study examined the distinct roles of chronotype and trait self-control in predicting sleep quality and found that trait self-control predicts sleep quality directly and indirectly through pre-sleep stress management and maintaining a restful sleep environment, whereas chronotype predicts sleep quality indirectly through pre-sleep stress management and bedtime media use. The study also showed that bedtime media use and irregular sleep timing are related to poor sleep quality in evening types, while environmental interference is more relevant to poor sleep quality in individuals low in self-control.

Summary: This study identified the correlates of bedtime procrastination and found that it was associated with self-control, evening chronotype, sleep duration, sleep quality, and daytime fatigue. Further high-quality research is needed to establish causal relationships between bedtime procrastination and these correlates, as well as its impact on sleep outcomes.

Summary: This study used a longitudinal self-control intervention experiment to investigate the impact of limiting bedtime smartphone use on the next-day working memory of individuals with problematic smartphone use. The experiment involved 156 Chinese undergraduates with problematic smartphone use who completed a 6-day experiment. The results showed that limiting smartphone use in bed improved next-day working memory. Therefore, limiting smartphone use in bed could potentially help alleviate daily cognitive impairments caused by problematic smartphone use.

Summary: A study conducted at the Black Dog Institute in Australia found that improving sleep through an app-based intervention can be a novel way to reduce depression among adolescents. The study evaluated the effectiveness of an app-delivered cognitive behavioural therapy program for insomnia called Sleep Ninja. The results showed that participants who received the intervention reported a greater reduction in insomnia symptoms and depression symptoms compared to the control group, with changes in insomnia mediating changes in depression.

Summary: This study found that participants with internet gaming disorder (IGD) performed worse in terms of intelligence, verbal comprehension, and processing speed compared to regular gamers and non-gamers. In the IGD group, Full Scale Intelligence Quotient (FSIQ), Verbal Comprehension Index (VCI), Working Memory Index (WMI), and Processing Speed Index (PSI) scores were significant predictors of gaming hours. Therefore, there is a need to strengthen working memory and verbal abilities to prevent the development of gaming addiction among high-risk gamers.
